To all whom, it may concern: .Y carriedby the car, to the cylinder O f-t'he car- Beit known that I, ADDISON C. RA'ND, acitif motor. y zen of the United States, residing in the city, In the drawings I have represented only county, and State-of NewYork, have invented such parts ofa pneumatic-car as are essen- 55 5 certain new and useful/Improvements in tial `to the understandingof my invention,

Pneumatic Vehicles, of which the following omitting such details of the number and is a full, clear, and exact description, referarrangementof the air storage reservoirs, ence being hadto the accompanying 'drawand of the motor itself, as well as the devices A' ings, forming part of this specification. which govern the operation thereof, as not 6o 1o My invention relates to' pneumatically being necessary to 'a comprehension of the l driven vehicles, such' as railway-cars,'which devices constituting my invention.

the combination therein, with the pipe'which Brepresents a compressed-air storage resconnects the air-storage reservoir to the moervoir carried bythe ca r, and usually located tor-cylinder, for the supply of air thereto, of belowI the cariioor, .as shown. an insulated chamber constituted in a`wall --B representenmotor-cylinder, which .isalso 7o zo of the vehicle, through which" chambersaid usually placed underneath the car-licor.. The

Within the chamber C Ilocate aheat-.ge'xlerator, which may be in the form of a gas- A5 burner D which encircles the pipefsections B2 at or near the lower-end of the chamber,-

1 the tips of said burner directing the gas-M lame toward and around said pipe-sections, as indicated in the drawings. More than a single burner muy be employed for the generation of heat in said chamber; and it is desir- `Y able to locate a burner near the upper part of vthe chamber, es, for example in the extension in the car-roof, as shown at D.

It will be' found advantageous to employ gas as the rneansfor generation of heat in the chamber C, in that the gas-supply may be carried in a. ccmnpressedI state in cylindrical reservoirs D2 which may be hung to the intec'ar-seats, as indicated in the' drawings, and a service-pipe or pipes d may connect the reservolr to the burners, as shown.

' '.By means of my invention the requisitev de-l vices or apparatus for eEecting the heating of the air supplied from the reservoir B to the motor-cylinder, or cylinders, are con* structed and arrsnged in a compactand inexpensive .'form, and, together with vthe gas ap. paratus for supplying the heatgenerators, are

capable of .combination with the car-body without occupy-ing otherwise available -sfpnce therein.
